Abstract
A lighting device that can be used, for example, in the show-business and entertainment sector includes an electrically powered light generator, as well as electrical circuitry configured to produce electrical signals for driving the light generator. The electrical circuitry has stored within it an electrical marker signal uniquely associated to the lighting device, and a visual display unit is coupled to the electrical circuitry, where the visual display unit is configured to display the electrical marker signal as a visually recognizable optical mark, such as a QR code.
